Taking pasta from boring to epic takes very little time and effort with this simple recipe for cottage cheese spaghetti!

Jarred Cottage Cheese Spaghetti Sauce
Sometimes, when I have a little more time, I make my cottage cheese pasta from scratch or even cottage cheese lasagna, but for nights when I’m in a hurry, this cottage cheese tomato sauce saves the day!
Sometimes we eat it plain, other times tossed with chicken pieces I cook in a pan. It’s versatile, and it makes me feel like I’ve got it together since my kids devour it without complaints. You can also add cottage cheese to chicken alfredo!

How to Make Cottage Cheese Tomato Sauce with a Jarred Sauce
You’re three steps away from the most epic and easy cottage cheese spaghetti! Check out the simple process and my tips to give this pasta sauce the perfect texture:
- Cook the pasta following the package directions. Once ready, reserve ½ cup of pasta water. You’ll use it later to thin the sauce.
- Blend the cottage cheese to yield a smooth texture that mixes well with the tomato sauce.
- Combine the tomato sauce and blended cottage cheese with the spaghetti. It will be thick. To thin it out, add some reserved pasta water until you get the desired consistency.

Does Cottage Cheese Melt in Sauce?
Cottage cheese doesn’t melt directly in the sauce; that’s why it needs to be blended first. Once blended and smooth, it will combine perfectly with the jarred tomato sauce.
How Much Protein is in Cottage Cheese Pasta Sauce
Each serving of spaghetti with cottage cheese tomato sauce contains about 20 grams of protein, making this pasta dinner a high-protein meal by simply including cottage cheese in the sauce!

Blending the cheese is a brilliant way to keep the texture smooth while still getting that extra creaminess in the red sauce. Reserving the pasta water to thin it out makes a massive difference for the consistency.
